But first : You have to bear in mind that System X is just a generic term for a whole load of different switches from loads of different manafacturers including Bell Laboratories (5AESS), GEC Plessey Telecom (TXE) Erriccson (AXE10) and British Telecom (Smaller Concentrators, MUX's + various other shit).
Anyway, I'll try to answer in relation to what I already know, so
dont be surprised if some of what I drool on about is partially or maybe
even fully wrong.
Question one : The editor for use via the ISDX Terminals
I wasnt aware of the actual name of the terminals used, and I always thought
that ISDX was a simple PBX/Caller Handler system. We have an ISDX unit
installed in my local probation office, so I'll take a closer look next time
I'm dragged in there...
However, as you seem particularly engrossed in the AXE10 in particular,
The name of the Interface and Editor is FIOL. It is simply referred to as
the FIOL interface, and I cant remember exactly what FIOL stands for.
Any other questions regarding interfacing? Its such a wide topic that you
could write a book on it.
Question Two : Other ways to talk to System X
As in Terminal wise, or simply testing or other facilities like REMOB's?
Theres the 174/5/6 tests, and there is usually a gamut of other test numbers
specific to each exchange, for individual testing and evaluation.
As for programming via a keypad, well, wouldnt we ALL love to know how to do
this? Im afraid I havent seen any paperwork referring to DTMF prognosis and
programming, but I'll keep scanning those patents and trashing those bins...
Question Three : How do you dial in?
Well, I dont work for BT, Contrary to Popular Belief and much to my personal
chagrin, so I cant really take it from that angle. I could quiz some
engineers, but I prefer not to mix with the enemy.
The switch can be accessed externally via the Operator SubSystem Dial-in,
a fatal flaw in the System X's otherwise impenetrable armour. This will
then allow you to control all customer switching and routing, and perform
ALL the usual operator thingies you can do, including:
Providing Directory Enquiries Tracing calls Placing Trunk calls Re-allocating Numbers Blah, Blah, Blah
Basically, it provides you with all the power of a full external operator,
regardless of where you call in from. Sound like fun? Yeah, but just try
and find the frigging dial-up, esp. if you live in an area served by a
mucho large exchange. Also bear in mind that even when you connect
(Its 2400, 8N1, No protocol, by the way) It will just sit there waiting for
a specific wake up string. I'm still working on this, and have been since
I first trashed my local switch.
Question four : Monitoring
Hmmm. That sounds like an interesting method, but a little bit to complicated.
The way I've seen it done (I SWEAR to SATAN, I DONT work for British Telecom!)
is to access the MMI (Man Machine Interface, or : Terminal. Doh.) and
to issue the local test access command. You then set up a speech path,
enter the access group of the number, its last six digits (Its only a local
test) and then enter either its equipment number or directory number.
This will allow you to monitor all the stuff you never hear on a normal
call, like Equal Access codes, MF tones, blah, blah, as well as the
conversation. Very boring. You've heard one, you've heard em all.
If you want more info on call monitoring or listening, then download the file entitled "Its your line to the phone tappers". It details how a line was tapped at the MDF in the old exchanges, and how it is now routed to the listening station Next to Victoria Station in London, via a few simple MMI commands.
